Abstract

L'invention concerne un dispositif d'extinction d'incendie rotatif sensible à la température, qui comporte un tuyau d'admission et un corps de gicleur. Le corps de gicleur comporte un capuchon de gicleur et un gicleur. Un noyau de robinet d'arrêt, dont l'extrémité supérieure est un robinet d'arrêt, est monté à l'intérieur du corps de gicleur. Un support est monté à l'extrémité inférieure du gicleur. Un élément sensible à la chaleur en verre est monté debout dans le support. Une extrémité de l'élément sensible à la chaleur en verre est insérée dans la vis de réglage du support, l'autre extrémité soutenant l'extrémité inférieure du robinet d'arrêt. Lors de l'amorçage, l'élément sensible à la chaleur en verre peut éclater automatiquement, le noyau de robinet d'arrêt, qui est supporté par l'élément sensible à la chaleur en verre, tombe pour faire sortir le robinet d'arrêt de l'orifice d'entrée d'eau qui est situé à l'extrémité inférieure du tuyau d'admission. L'eau entre alors immédiatement dans la chambre et jaillit de l'orifice de sortie. En même temps, une force impulsionnelle inverse est appliquée sur le corps du gicleur pour le faire tourner par son roulement à billes. La force centrifuge produite par la rotation du corps de gicleur fait sortir l'eau en un jet de forme parabolique, pour couvrir ainsi une plus grande zone lors d'un incendie.
